RESUMO
Objective:To investigate the targeted surveillance combined with cluster management on isolation protector use rate and hand hygiene qualification rate in caregivers of patients with respiratory tract multidrug-resistant bacterial infections.Methods:Second Hospital of Shanxi Medical University began to perform targeted surveillance combined with cluster management among caregivers of patients with multidrug-resistant bacterial infections in July 2019. The caregivers of 50 patients with respiratory tract multidrug-resistant bacterial infections who were admitted before targeted surveillance combined with cluster management were included in the pre-implementation group. The caregivers of 50 patients with respiratory tract multidrug-resistant bacterial infections who were admitted after targeted surveillance combined with cluster management were included in the post-implementation group. Multidrug-resistant bacterial infections in caregivers, isolation protector use rate, environmental disinfection and hand hygiene qualification rate were compared between before and after 6 months of targeted surveillance combined with cluster management. The application value of targeted surveillance combined with cluster management in the prevention of respiratory tract multidrug-resistant bacterial infections was analyzed.Results:The number of caregivers with respiratory tract multidrug-resistant bacterial infections in the post-implementation group was lower than that in the pre-implementation group (5 vs. 13, P < 0.05). The proportion of caregivers who wear a mask (94.11%), isolation clothes (80.39%) and gloves (98.03%) in the post-implementation group was significantly higher than that in the pre-implementation group (70.00%, 62.00%, 78.00%, χ2 = 10.027, 4.911, 9.683, all P < 0.05). The proportion of caregivers who were qualified in terms of hand hygiene (82.35%), object surface (76.47%), and keeping the air fresh in the post-implementation group was significantly higher than that in the pre-implementation group (64.00%, 58.00%, 64.00%, χ2 = 4.341, 3.915, 5.450, all P < 0.05). Conclusion:Targeted surveillance combined with cluster management can effectively help prevent respiratory tract multidrug-resistant bacterial infections in caregivers and increase isolation protector use rate and hand hygiene qualification rate.
RESUMO
Magnetic resonance imaging (MRI) is a very important imaging method for diagnosis and treatment of prostate cancer (PCa) in clinical practice. As functional MRI is growing and maturing, its quantitative parameters are expected to enhance the clinical value of MRI furtherly. Intravoxel incoherent motion diffusion imaging, diffusion tensor imaging, and diffusion kurtosis imaging, which were derived from diffusion weighted imaging, have provided richer and more accurate parameters. The newly-developed magnetic resonance elastography can complement the mechanical characteristics of PCa.
